NO
The purpose of this study was to investigate the clinical usefulness of iFR in coronary artery lesions with prior myocardial infarction.
Efficacy

Male and Female
Patients with stable angina pectoris performed diagnostic coronary angiogram and physiological assessment with iFR and FFR
1) previous coronary bypass grafting
2) hemodialysis
3) lesion of pMI without myocardial viability assessed with echocardiogramphy or cardiac magnetic resonance imaging (MRI)
4) clinical history of MI with non-target legion
5) chronic total lesion
6) tandem lesion; a major native coronary artery with >=2 stenoses separated by a more normal segment.

In pMI lesions, an iFR cut-off of 0.89 was optimal against a clinical FFR cut-off of 0.80 according to receiver oper- ating characteristics (ROC) curve analysis, whereas in non-pMI lesions, the iFR cut-off value was 0.92 without statistical significance. I

Two-hundred consecutive patients with stable coronary artery disease (CAD) who underwent diagnostic coronary angiogram and physiological assessment with iFR and FFR were retrospectively enrolled from 4 hospitals in Japan from May 2014 and July 2016.
The patients were divided into two groups according to the presence or absence of pMI.
None
